2000 mustang making whistle sound??
Ok so i recently got my car back after a new motor and heads/cam install and now its making a whistling noise and stalling out on occasion...
Car is tuned.. cams are baby cams 262XE with stage 2 patriot heads
doesnt seem to do it untill the car warms up and has been running for a little bit... then it will do it every other stoplight...
any idea???
kinda pissing me off...lol

Yea its at the shop right now...
side note... i'm hovering around 285rwhp through manifolds
could a bottle neck in the exhaust (manifolds) cause enough of a breathing problem that it could choke down the motor?
and an oil breather cap... thats not neccesary.. i'd assume not since my car isnt anything special...
maybe they felt sorry for my mustang and hid a tiny turbo somewhere...ahaha...

no your manifolds won't cause that. like 99gtvert said check connections, I thought maybe a vacuum leak, cause that would cause whistling and the motor to die, but it should do it all the time

I have heard of this happening after cam install, mine is actually making a whistling sound as well since installing the cams. it does not cut out though. I have checked everything and cant figure out where its coming from. sounds like it has a s trim on it.

RE: 2000 mustang making whistle sound??
yea so my car sounds like it has a blower on it...
One of the hoses had colapsed cutting off air into the inlet next to the IAC valve
But I have heard that on some motors that high crankcase pressure can cause a whistle and usally allevated by using a oil breather cap...
But i cannot find one for a 2v mustang... ideas???

There's your idle problem. I assume you fixed it.

In any situation its always better to run a breather on one side or at least a catch can. Especially with new cams/heads installed you will experience significant amount of oil consumption through the intake without it.

You may need to find a small adapter or make one somehow, but try any of the auto parts stores. They should have small breather caps made by K&N, Mr. Gasket, or a number of brands.
PS - Make sure one side is sucking or "pulling" and the other side is open through the breather.
